What Do We Call Bill Clinton If Hillary Wins?

First... dude?

Hillary Clinton was known as the 'First Lady' during her husband, Bill's, time as President.

But should Hillary defeat Donald Trump in the US election today, what will be Bill Clinton's official title?

It's an unprecedented question - and as such has no formal answer.

Hillary was quizzed on the topic throughout the campaign trail - and it appears she has made up her mind.

“I think part of what we’ll have to figure out is what do you call the male spouse of a female president,” she said.

“Now, it’s a little bit more complicated with him because people still call former presidents Mr President. So I have to really work on this.”

“I’ve already told my husband that if I’m so fortunate enough to be president and he will be the First Gentleman, I expect him to go to work to make sure we get those jobs growing and incomes rising,” she said at a campaign event.

So there you have it - should Americans vote for Hillary in the historic election, Bill's got a formal title to use.
